2 Safety

2.1 Intended UseThe SMA RS485 Module enables SMA inverters to establish wired RS485 communication.The RS485 Module must only be installed in the following SMA inverters:

• STP 50-40 (Sunny Tripower CORE1)The inverter still complies with the standard after the product has been installed.The product must only be used in countries for which it is approved or released by SMA SolarTechnology AG and the grid operator.All components must remain within their permitted operating ranges and their installationrequirements at all times.Use this product only in accordance with the information provided in the enclosed documentationand with the locally applicable standards and directives. Any other application may causepersonal injury or property damage.Alterations to the product, e.g. changes or modifications, are only permitted with the express writtenpermission of SMA Solar Technology AG. Unauthorized alterations will void guarantee andwarranty claims and in most cases terminate the operating license. SMA Solar Technology AGshall not be held liable for any damage caused by such changes.Any use of the product other than that described in the Intended Use section does not qualify as theintended use.The enclosed documentation is an integral part of this product. Keep the documentation in aconvenient place for future reference and observe all instructions contained therein.The type label must remain permanently attached to the product.

2.2 Safety InformationThis section contains safety information that must be observed at all times when working on or withthe product.To prevent personal injury and property damage and to ensure long-term operation of the product,read this section carefully and observe all safety information at all times.

Danger to life due to high voltages of the PV arrayWhen exposed to light, the PV array generates dangerous DC voltage, which is present in the DCconductors and the live components of the inverter. Touching the DC conductors or the livecomponents can lead to lethal electric shocks.

• Prior to performing any work on the inverter, always disconnect the inverter from voltagesources on the AC and DC sides as described in the inverter manual. When doing so, notethat even if the DC load-break is switched off, there will be dangerous direct voltage presentin the DC conductors of the inverter.

2 Safety SMA Solar Technology AG


Damage to seals on the enclosure lids in subfreezing conditionsIf you open the enclosure lids when temperatures are below freezing, the enclosure seals can bedamaged. This can lead to moisture entering the inverter.

• Only open the enclosure lids if the ambient temperature is not below -5°C• If a layer of ice has formed on the seal of the lid when temperatures are below freezing,

remove it prior to opening the enclosure lids (e.g. by melting the ice with warm air). Observethe applicable safety regulations.

Damage to the inverter or product due to electrostatic dischargeTouching electronic components can cause damage to or destroy the inverter or the productthrough electrostatic discharge.

• Ground yourself before touching any component.

5.2 Installing the ModuleMaximum number of modules per inverterYou can only use a maximum of one module of the same device type per inverter.

Procedure:1.

Danger to life due to high voltages of the PV arrayWhen exposed to sunlight, the PV array generates dangerous DC voltage, which is present inthe DC conductors and the live components of the inverter. Touching the DC conductors or thelive components can lead to lethal electric shocks.

• Prior to performing any work on the inverter, always disconnect the inverter from voltagesources on the AC and DC sides as described in the inverter manual. When doing so,note that even if the DC load-break is switched off, there will be dangerous direct voltagepresent in the DC conductors of the inverter.

2. Remove the enclosure lid of the DC Connection Unit. Unscrew all screws with a Torxscrewdriver (TX 25) and remove the enclosure lid carefully forward.

3. Set the screws and the enclosure lid aside and store safely.

5 MountingSMA Solar Technology AG


4. Install the module at the desired mounting location. Perform the following steps:• Guide the three guide pins on the

communication assembly through the holesin the module. The holes in which the guidepins must be inserted depend on themounting location.

• Carefully push the module down on theupper edge and on the connection socketsuntil it audibly snaps into both side lockingtabs of the communication assembly. Theconnector strip on the back of the module isautomatically pushed into the socketterminal strip of the communicationassembly.

5. Screw tight the fastening screw with a Torxscrewdriver (TX 25) on the module (torque:1.5 Nm). This additionally fixes the module inplace and grounds it in the inverter enclosure.

6 Connection

6.1 Preparing the Connection CableDepending on whether the module is located at the end or in the middle of the communication bus,prepare one or two connection cables as described in the following.

Requirements:☐ The cable requirements must be complied with (see Installation Instructions "RS485 Cabling

Plan" at www.SMA-Solar.com).☐ Diameter of the cable when using the cable support sleeve with one hole: at maximum

17 mm☐ Diameter of the cable when using the cable support sleeve with two holes: at maximum

6.5 mm

Procedure:1. Strip 40 mm of cable sheath from the end of the connection cable to which the terminal block

is to be attached. Make sure that no pieces of cable are dropped into the inverter.2. Trim the cable shield to a length of 15 mm and

fold it over the cable sheath.

3. Wrap the cable shield with copper foil.

4. Strip the insulation on the three insulated conductors each by 6 mm. The two insulatedconductors used for communication must be a twisted pair.

5. Trim unneeded insulated conductors of the connection cable flush with the cable sheath.

6.2 Inserting the CablesAdditionally required material (not included in the scope of delivery):

☐ Connection cable (see Section 6.1, page 13)

6 ConnectionSMA Solar Technology AG



Procedure:1. Make sure that the inverter has been disconnected and is secured against reconnection (see

the inverter manual).2. Remove the swivel nut from the cable gland for the communication cable.3. Thread the swivel nut over the cable.4. Press the two-hole cable support sleeve out of the cable gland.5. Remove the sealing plug from one of the enclosure openings of the two-hole cable support

sleeve and insert the cable into the enclosure opening.6. Press the two-hole cable support sleeve with the cable into the cable gland and guide the

cable to the communication assembly in the DC Connection Unit. Ensure that any unusedenclosure openings of the two-hole cable support sleeve are sealed with sealing plugs.

7. Tighten the swivel nut on the cable gland hand-tight. This will secure the cable.
